Volcanic+Eruption+Events

=Volcanic Eruption Events = Volcanic Eruption plays a bigger part than you may think....

- That after the eruption of Mount Pinatubo in 1991 the average global temperature decreased about a degree Fahrenheit for two years.
-That after the eruption of Tambora in 1815 the temperature dropped causing crop failures and famine for approximately two years as well. -That the [|tallest volcano] isn't even on earth? Its on Mars! -Volcanoes mostly cause a **DECREASE ** in temperature, but they are also responsible of natural CO2 in the atmosphere, so therefore can cause an increase as well.

More information about past volcanic eruption events of disaster is here at this [|volcano time-line]site.

WHAT SURPRISES ME IS:
That multiple eruptions of giant volcanoes, over time, can raise carbon dioxide levels enough to cause significant [|GLOBAL WARMING]! Volcanoes have a direct connection to global warming, which is current events, and an issue we need to address,
 * VOLCANOES CAUSE A DECREASE IN TEMPERATURE! **

==During Volcanic Eruptions, the gases and dust particles, or [|volcanic ash], are exposed into the atmosphere which results in either warming or cooling the earths surface; depending on the sun.==

Visual of volcanic dust; ASH:

Volcanic dust causes a cool temperature in the atmosphere, the temperature depends on the amount, size, and duration of the dust in the atmosphere. If they are sand grains, they stay close to the volcanoes and barely have any effect on the climate, if they are tiny DUST size, they travel through the atmosphere for days, and weeks which creates a "cloud" and blocks the sunlight causing a cool temperature.
 * VOLCANIC DUST: **

When volcanoes releases sulfur oxide or [|sulfur] dioxide, climate changes even more so than the volcanic dust. Volcanoes releases water and carbon dioxide and essentially when two compounds that are in the form of gas are in the atmosphere, they absorb heat radiation, which causes the air below to get warmer. Which as mind boggling as it may seems results in a cooling temperature; the dioxide dissolves in the ocean and such, and the sulfur compounds dominate the situation.
 * Volcanoes releasing sulfur compounds: GASES ARE MAJOR FACTORS OF CLIMATE CHANGE **

Tropical Volcanoes cause a larger impact than non tropical volcanoes: The sulfur particles in the tropical air raise higher up in the [|stratosphere] than in non tropical regions.

CAUTION; VOLCANOES are very hazardous and dangerous. [|Volcanic risk.]

There are different [|types of volcanic eruptions:]

Hawaiian Eruption: 

Strombolian Eruption:

Vulcanian Eruption Plinian Eruption: Lava Domes Surteyan Eruption

Ways to determine the eruption type are focusing on the crystal and gas content and temperature of a mangma.
